rel aims, (ci ia- 48y- I n generators of producers forthe production of gas, more particularly water gas, mechanical and automaticrernoval of fthe clinker formed'dur Ming the 'operation'of gas making is effected by 5 means of a grate adapted to break up the clinker masses and automatically remoye the clinker and ashes from the fuel bed.

It is desirable toremove the clinker and ashes continuously or with as little interruption of gas 10 making as possible, and, in one method, the

clinker and ashes are made to pass through a r i let 2 having a valve z therein. Theseserve re-- spectively for the admission of air and steam for water seal such as for instance is provided by a water-containing ashpan in conjunction with a wall 01' apron depending from the generator under which the clinker and ashes are continuously expelled to the outside without any interruption of gas making, In some cases, this water sealed ashpan is dispensed with and the generator entirely enclosed at the bottom, in which case pockets or receptacles are formed in, and are pendant from, the casing of the generator into which pockets or receptacles the clinker and ashes are expelled and the gas making has to be interrupted in order to discharge the accumulated clinker and ashes periodically, the intervals between discharges depending on the size of the pockets or receptacles.

Generally it is found inconvenient to provide such pockets or receptacles of a capacity larger 3 thansufilcient to hold a few hours supply of clinker and ashes; therefore it is necessary to interrupt gas making a corresponding number of times daily in order to discharge the ash hoppers and there is consequent, loss of gas production and 1disturbance of the uniformity of operating condiions.

The object of this invention is to enable a generator or producer of the dry or totally enclosed type to be operated with the same advantages as 40 regards continuous operation as an open or water sealed generator or producer.

For this purpose, according to the present invention, the clinker and ash receiving pocket or each such pocket of a mechanically clinkered gas generator or producer of the totally enclosed type is provided with means adapted to permit the discharge of clinker and ash therefrom during the operation of the generator orproducer without permitting the passage of gas or air through the of pocket with means adapted to permit discharge of clinker and ash without passage'of gas according to the invention is shown,

,u is the wall of the generatoncombustible gas, I; is a revolving grate containing a ruel'bed b of'coal, coke orthe'like with'perforated'drum c having perforations c" therein, d aplinker aridf ash ,discharge'pa'ssage from aboye'the gratand e the pocket or receptacle; there may be' more that one such receptacle. The generator 0. has

an air inlet 1: having a valve m therein, a-steam 10 v inlet y having a valve y therein, and a gas outuprun gas making and for the outlet of downrun gas. The grate b is provided with age'ar 1' which 15 is driven by a worm w to rotate the grate. Closures such as hinged doors ,f and dfor closing the inlet to and the outlet from the pocket j are provided and the closures are interlocked in such manner that they cannot both be open or partially open at the same time but that either: can be opened when the other is completely closed. The inlet door ,fis shown hinged on pin f. within the pocket and the outlet door 9 is shown hinged on pin 9 externally thereof and the hinge pins ,"f and g are extended andprovided with interlocking mechanism which will prevent ei ther being turned to open unless the other be closed In the example the hinge pins have fixed to them Y sector-shaped plates F, g and a slidingbar h 30 serves by engagement with the end of oneor other of the plates F, g to interlock the doors) and g; the bar It has Wedge shaped ends h ',"h, which by engaging the end of the sector shaped plate of the closed door serve to force the door 35 into close contact with its seat. The sliding bar It is mounted in a bearing 1 and supported near its ends by abutments 9'. k is a lever for moving the bar h, and this lever may be connected by a rod-l I to any suitable form of interlocking mechanism 40 whereby the outlet door 9 is interlocked with the,,,- operating gear of the reversing valve (not shown). of the generator or producer so that the door-"d cannot be opened while gas is being made inadownward direction in the generator or produce Having now particularly described and ascer tained the nature of my invention and in what manner the same is to be performed I declare tl'i whatI claim is:
